<span>Minerals are inorganic molecules that perform important and vital functions in the body. The body can not make minerals and must consume them through a varied and healthy diet. Examples of minerals include boron, calcium, phosphorus, magnesium, potassium, iron, zinc, and sodium.</span>
Answer:
B. He has no E alleles.
Explanation:
In order for the boy to have an attached earlobes phenotype, he must have no E alleles, because the E is dominant. So his genotype must be ee. If he has even just a single E allele (like Ee) he will have detached earlobes, because the dominant trait will mask the expression of the recessive trait.
Why not A or D: Heterozygous Ee (one of each allele) would result in detached earlobes.
Why not C: If he has no recessive alleles, EE, he would have detached earlobes.
Answer:
e. This process produces 2 molecules of NAD+ starting from 2 molecules of NADH
Explanation:
Glycolysis or EMP pathway is first stage of cellular respiration. It takes place in the cytoplasm of the cell. During glycolysis one 6 carbon glucose is converted into two molecules of 3 carbon pyruvic acid or pyruvate. This conversion does not require oxygen and in the process there is net gain of 2ATP. Along with ATPs, in the process of glycolysis, 2 electron carrying molecules NADH are produced from NAD⁺. Thus, option e. is not true.
